It was used in GTA3. After you collected all gars form Import/Export garage, there were pickups spawned. After you picked one, the garage gave you a vehicle you like. It is available in other GTA games as a leftover and has no use, unless you script it.

Oh, i didn't play GTA III much, so i didn't know it.The leftover from SA is possibly because of the Engine the game runs on.
